On Saturday, April 18, and Sunday, April 19, 2026, the large-scale participatory program "PEACE FLOWER GARDEN," themed on war and peace, will be held at "Earth Day Tokyo 2026" at Yoyogi Park.
Earth Day is a day when hundreds of millions of people in over 190 countries and regions around the world think about the Earth on the same day. As Japan's largest base for this, Earth Day Tokyo attracts over 100,000 visitors every year, providing a place to think about the future from various perspectives.
In 2026, with "Peace" set as a key theme, we will roll out "peace actions" that every single citizen can participate in amidst this modern era of increasing division.
From Weapons to Flowers ── Participatory Art "PEACE FLOWER GARDEN"
The symbol of this initiative is the "PEACE FLOWER GARDEN" by the art projects "retiredweapons" and "greenpiece ― memento mori project."
With the cooperation of Hibiya Kadan, an installation will be deployed where flowers are inserted into weapons, transforming "symbols of destruction" into "symbols of prayer."
"retiredweapons" is an international project that has been highly acclaimed at overseas design events in Milan, Berlin, and London.
It is a participatory artwork completed by visitors actually inserting flowers, and you can photograph how the scenery of the venue changes over time.
A Message from Mr. Ichikawa Danjuro for the Event
We received a message for the hosting of Earth Day Tokyo 2026 from Kabuki actor Mr. Ichikawa Danjuro, who is also the Representative Director of the certified NPO Earth&Human.
"We who live on this Earth are by no means isolated entities, but are kept alive within the great workings of nature and deep connections between people.
However, with the progress of civilization, that spirit of harmony is fading.
Now more than ever, aren't we required to regain that spirit?
I hope that this place will bring new realizations and encounters, and become a beacon of hope passed down to the next generation."
*This message is a supportive comment for the event, and he is not scheduled to visit the venue on the day.
